  • Title: Genetic evidence for the relationship of Porphyromonas gingivalis cysteine protease and hemagglutinin activities.

    Journal: Oral Microbiol Immunol; 1996 Jun; 11(3):129-34. PubMed ID: 8941765.
    Abstract:
    Cysteine protease and hemagglutinin activities of Porphyromonas gingivalis have been implicated as virulence factors in periodontitis. In addition, a close structural relationship between these factors has been suggested. In order to examine the molecular basis for such a relationship, we constructed an isogenic mutant, G-102, of P. gingivalis 381 deficient in Arg-gingipain cysteine protease activity. The mutant displayed not only reduced protease activity but also significantly reduced hemagglutination activity compared with the wild-type strain. Therefore, this investigation provided genetic evidence for the recently proposed structural relationship between Arg-gingipain and the hemagglutinin activity of P. gingivalis strains.
